Kansas freshman Andrew Wiggins announced his plans to declare for the NBA draft on Monday, ending his short year with the Jayhawks and following the expected one-and-done path to the league.

Wiggins is a projected lottery pick and could be the top overall choice based on his upside. Fellow Kansas freshman Wayne Selden Jr. has already announced he will return to school. Freshman center Joel Embiid, who also has a chance to be the top overall pick, has yet to announce his plans.

"It wasn't an easy decision," Wiggins said in a scheduled news conference of his decision not to stay at KU. "I just wish I had more time. It went by so fast."

Wiggins' lone college season started with an incredible buzz but ended on a sour note with a poor performance in Kansas' second-round NCAA tournament loss to Stanford.

"No one's game is perfect, I know I have a lot I have to improve on," Wiggins said.

He entered college as the most touted high school prospect arguably since LeBron James. He was on the cover of Sports Illustrated before he played a game, and even his arrival on campus last summer sparked significant attention.

Throughout the season, Wiggins played the way he often did in high school at Huntington Prep (W.Va.). At times, he showed flashes of offensive brilliance and freakish athletic ability on a balanced Kansas team. At other times, he appeared to blend in or, worse, appear invisible on the court.

"I feel for Wiggins every day," SMU coach Larry Brown told USA TODAY Sports recently. "You hear one game, 'Oh, he's the first pick.' Then the next game, 'Oh, I'm so disappointed.' That stuff drives me crazy. He's a 19-year-old freshman. He is a special kid."

Wiggins does not naturally and consistently exhibit a killer instinct or assertiveness on the court. But he was Kansas' best defensive player during long stretches this season. He showed some signs of assertiveness offensively late in the season, including authoring a 41-point effort in a loss at West Virginia on March 8.

But he finished his brief college career with a four-point effort in Kansas' third-round NCAA tournament loss to Stanford.

Jordan Adams, UCLA sophomore: The high-scoring shooting guard intially was going to return to school after averaging 17.4 points a game. The 6-5 natural wing could be a late first-rounder.

Isaiah Austin, Baylor sophomore: The 7-foot center helped the Bears reach the Sweet 16 in 2014 and averaged 11.2 points and 5.5 rebounds a game. But his rail-thin physique has scouts worried, and he probably will be a second-rounder.

Chane Behanan, Louisville junior: The undersized power forward was a key factor on the 2013 championship team but was kicked off last year's Cardinals midseason. He might be tough enough to scrape his way into the NBA but probably will have to start in the Development League.

Sim Bhullar, New Mexico sophomore: The tallest player in Division I at 7-5 averaged 10.4 points on 64.8% shooting, 7.8 rebounds and 3.4 blocks a game. Durability and mobility are issues, though, and he is expected to fall to the second round.

Khem Birch, UNLV junior: Birch was the Mountain West Conference defensive player of the year in each of his two seasons at UNLV after transferring from Pittsburgh. As a junior, he averaged 11.5 points and 10.2 rebounds and was second in the country with 3.8 blocks.

Jabari Brown, Missouri junior: The shooting guard was a transfer from Oregon and broke out in his second season with the Tigers, averaging 19.9 points a game and shooting 41.0% from the field. He could be a first-round pick but more likely will fall to the second.

Jahii Carson, Arizona State sophomore: The 5-10 point guard has tremendous scoring ability and improved his decision-making in his second season. He is a good enough athlete to make a dent in the NBA and could be a late first-rounder.
Rick Scuteri, USA TODAY Sports

Semaj Christon, Xavier sophomore: The athletic point guard started the season as a potential top-10 pick but didn't develop as much as expected. He still could go in the late lottery.
Brad Penner, USA TODAY Sports

Jordan Clarkson, Missouri junior: The Tulsa transfer lit up the Southeastern Conference at times, averaging 17.5 points, 3.8 rebounds and 3.4 assists a game. If he can convince people that he is a true point guard, he'll go in the top 20, but the late first round is more likely.

Spencer Dinwiddie, Colorado junior: The point guard led the Buffaloes to a 14-2 record before suffering a torn left ACL on Jan. 12. He averaged 14.7 points, 3.8 assists and 3.1 rebounds, but his injury and a deep draft class could land Dinwiddie in the second round.

Tyler Ennis, Syracuse freshman: The heady point guard showed great tenacity in the clutch but still has a lot of development to do. His potential should keep in him in the midddle of the first round.
Kevin Hoffman, USA TODAY Sports

Aaron Gordon, Arizona freshman: One of the nation's most hyped recruits delivered on his potential in averaging an efficient 12.4 points and 8.0 rebounds a game. But at 6-9, 225 pounds, he may not have the size to play power forward in the NBA. He should be a lottery pick either way.

Jerami Grant, Syracuse sophomore: The 6-8 combo forward is a great athlete with developing ball skills. He averaged only 12.1 points and 6.8 rebounds a game last season but still could land in the top 20.
Rich Barnes, USA TODAY Sports

P.J. Hairston, North Carolina/Texas Legends: Barred by the NCAA from playing for the Tar Heels, the swingman went to the Development League and dominated, averaging 21.8 points a game. He should be a first-rounder after that production.
Rob Kinnan, USA TODAY Sports

Gary Harris, Michigan State sophomore: The 6-4, strong and smooth shooting guard has the potential to start right away in the NBA. He averaged 16.7 points a game but moreover was an excellent defender who played within the team. Harris projects to be a lottery pick.
Kirby Lee, USA TODAY Sports

Nick Johnson, Arizona junior: The best player on one of the best teams in the country averaged 16.3 points, 4.1 rebounds and 2.8 assists a game. He now needs to prove to teams he can play point guard full time, which he has the skillset to handle. If he does, he will be a first-rounder.
Christopher Hanewinckel, USA TODAY Sports

Zach LaVine, UCLA freshman: The athletic, skilled guard has loads of potential but didn't fully display that ability in his first year. Teams are excited enough by his upside to draft him in the middle of the first round.
Nelson Chenault, USA TODAY Sports

James Michael McAdoo, North Carolina junior: After a disappointing three years with the Tar Heels, the forward is expected to be drafted in the late first or early second round. He has a good scoring touch at times but disappears often.

Mitch McGary, Michigan sophomore: Facing a year suspension for a marijuana test, the big man decided to enter the NBA draft despite missing most of last season with a back injury. He averaged 9.5 points and 8.3 rebounds a game and has enough potential to be picked in the second round.
Rick Osentoski, USA TODAY Sports

Eric Moreland, Oregon State junior: The 6-10 forward averaged 8.9 points and 10.3 rebounds a game for the Beavers. He might be a second-round pick or return for his senior year to work on his offense.

Johnny O'Bryant III, LSU junior: The sturdy power forward likely is testing the waters, which players may do once if they do not sign with an agent. But he was one of the SEC's most productive players.
Crystal LoGiudice, USA TODAY Sports

Julius Randle, Kentucky freshman: The gifted power forward was the Wildcats' main catalyst en route to the national title game and averaged a double-double (15.0 points and 10.4 rebounds per game). He could be a top-four pick.

Glenn Robinson III, Michigan sophomore: The son of a former No. 1 overall pick won't go that high after stagnating a bit in his second college season, averaging 13.1 points and 4.4 rebounds a game. But he has great athleticism and instincts and should be a first-rounder.
Bob Donnan, USA TODAY Sports

LaQuinton Ross, Ohio State junior: The talented but inconsistent small forward could be a candidate to return to school. If he sticks in the draft, he likely will be a second-round pick.

JaKarr Sampson, St. John's sophomore: The small forward was one of the biggest surprises to declare. Even after a productive season, he probably at best will be drafted in the late second round.

Denny Medley, USA TODAY Sports

Nik Stauskas, Michigan sophomore: The player of the year candidate is a top-tier shooter who can create off the dribble for himself and teammates, as shown by his 17.5 points and 3.3 assists a game. He will be a top-20 pick and could land in the top 10.
Jeff Hanisch, USA TODAY Sports

Noah Vonleh, Indiana freshman: The lanky forward has the size and strength to play inside and showed great rebounding ability last season. He could be drafted in the top five.
Pat Lovell, USA TODAY Sports

T.J. Warren, North Carolina State sophomore: The Atlantic Coast Conference's top scorer was remarkably productive but still lacks an ideal jump shot. He should be a mid-first-rounder.
Kim Klement, USA TODAY Sports

Andrew Wiggins, Kansas freshman: The small forward entered the season as the odds-on favorite to be the No. 1 pick in this loaded draft. After an uneven first year, that is not quite as much of a guarantee. But he showed enough potential to merit the top spot, should he land it.
Scott Rovak, USA TODAY Sports

James Young, Kentucky freshman: The well-rounded swingman was lost at times with the Harrison twins running Kentucky's offense, but he still averaged 14.3 points a game and should be a top-20 pick.
